mlreportgen.report.Report Class

Namespace: mlreportgen.report

Report container

Description

An object of the mlreportgen.report.Report class is a container for a report consisting of reporters and MATLAB^® and DOM objects. Use an mlreportgen.report.Report object to generate an HTML, PDF, or Word report based on templates in a template library.

Note

To create reports with Simulink^® or Stateflow^® content, use the slreportgen.report.Report (Simulink Report Generator) class.

The mlreportgen.report.Report class is a handle class.

Class Attributes

HandleCompatible

true

For information on class attributes, see Class Attributes.

Creation

Description

report = mlreportgen.report.Report returns a report container object with default property values.

report = mlreportgen.report.Report(path) sets the OutputPath property to path.

report = mlreportgen.report.Report(path,type) also sets the Type property to type.

report = mlreportgen.report.Report(path,type,template) also sets the TemplatePath property to template.

report = mlreportgen.report.Report(Name=Value) sets properties using name-value arguments. You can specify multiple name-value arguments in any order.

Properties

OutputPath — Path of generated report file

character vector | string scalar

Path of the generated report file, specified as a character vector or string scalar. The path is the location in the file system of the report output document. The path can be a full path, for example, "C:/myreports/reportA.docx". The path can also be relative to the current MATLAB folder, for example, "reportA". If the file name does not have a file extension that corresponds to the Type property, the report generator adds the appropriate file extension when the report document is closed.

Note

Generating a PDF report on a cloud drive, such as MATLAB Drive™ or Microsoft^® OneDrive™, can cause file contention between the report generation software and the cloud drive synchronization software resulting in a version of this error:

Error closing document package: Could not commit changes: removeAll failed: fl:filesystem:AccessDenied: 
C:\Users\jdoe\OneDrive\Documents\MATLAB\reports\temp_FO\stylesheets: Permission denied.

To avoid this issue, generate reports on a local drive that does not synchronize with the cloud. Consider writing a script that generates a report on a local drive and then copies the report to the cloud drive.

Data Types: char | string

Type — Output type

"pdf" (default) | "docx" | "html" | "html-file" | "pdfa"

Output type, specified as one of these values:

• "docx" — Microsoft Word document.

• "html" — HTML report, packaged as a zipped file that contains the HTML file, images, style sheet, and JavaScript^® files of the report. To generate an HTML report as a folder that contains unzipped files, set the PackageType property to "unzipped" or "both".

• "html-file" — HTML report that consists of a single HTML file that contains the text, style sheets, JavaScript, and base64-encoded images of the report.

• "pdf"— PDF file.

• "pdfa" — PDF/A file. (since R2025a)

If you specify a template using the TemplatePath property, the value for Type must match the template type.

Data Types: char | string

PackageType — Packaging to use for generated files

"zipped" (default) | "unzipped" | "both" | "single-file"

Packaging to use for the generated files, specified as one of these values:

Value	Supported Report Types	Description
"zipped"	"docx" "html"	Generates the report as a ZIP file at the location specified by the OutputPath property. The ZIP file has an extension that matches the document type (.docx for Word output or .htmtx for HTML output.) For example, if the document type is "docx" and OutputPath is s:\docs\MyDoc, the output is in a ZIP file named s:\docs\MyDoc.docx.
"unzipped"	"docx" "html"	Generates the report as separate files in a folder that has the file name of the OutputPath property. For example, if the OutputPath is s:\docs\MyDoc, the output folder is s:\docs\MyDoc.
"both"	"docx" "html"	Generates zipped and unzipped outputs.
"single-file"	"html-file" "pdf" "pdfa" (since R2025a)	Generates the report as a single file.

Tip

To generate an HTML report that you can open without unzipping when the Type property is "html", set PackageType to "unzipped" or "both". In the folder that contains the generated files, open the root.html file.

Locale — Locale or language

[] (default) | "af" | "ca" | "cs" | ...

Locale or language, specified as a character vector or string scalar that consists of the ISO_639-1 two-letter language code of the locale for which this report is to be generated. The default value, [], specifies the language of the system locale, for example, English on an English system. The Report API uses the language code to translate chapter title prefixes to the language of the specified locale. Translations are provided for the following locales:

• "af"

• "ca"

• "cs"

• "da"

• "de"

• "el"

• "en"

• "es"

Layout — Page layout options

mlreportgen.report.ReportLayout object

Page layout options for this report, specified as an mlreportgen.report.ReportLayout object. The default value of the Layout property is an mlreportgen.report.ReportLayout object with default values. Customize the page layout by modifying the property values. For an example, see Create a Landscape Report.

The layout options specified by the Layout property of objects of the mlreportgen.report.TitlePage, mlreportgen.report.TableOfContents, and mlreportgen.report.Chapter classes can override the page layout properties specified by the Layout property of an mlreportgen.report.Report object.

Note

The Layout property applies only to PDF and Word reports.

Examples

Create a Report

Create a report using the Report API.

Import the DOM and Report API namespaces so that you do not have to use fully qualified class names.

import mlreportgen.report.*
import mlreportgen.dom.*

Create the report container.

rpt = Report('My Report','pdf');

Add a title page, table of contents, and chapter to the report. The chapter contains two sections, each of which contains an image.

append(rpt,TitlePage(Title='My Report'));
append(rpt,TableOfContents);
ch = Chapter('Images');
append(ch,Section(Title='Boeing 747',...
    Content=Image(which('b747.jpg'))));
append(ch,Section(Title='Peppers',...
    Content=Image(which('peppers.png'))));
append(rpt,ch);
close(rpt);
rptview(rpt);

Create a Landscape Report

Create a report that has landscape orientation by using the Report API.

Import the Report API namespaces so that you do not have to use long, fully qualified class names.

import mlreportgen.report.*

Create a report container. In the mlreportgen.report.ReportLayout object assigned to the Layout property, set the Landscape property to true.

rpt = Report("myreport","pdf");
rpt.Layout.Landscape = true;

Add content to the report. Generate and view the report.

append(rpt,TitlePage(Title="My Landscape Report"));
append(rpt,TableOfContents);
append(rpt,Chapter(Title="Tests"));
append(rpt,Chapter(Title="Unit Tests"));
close(rpt);
rptview(rpt);

Specify a Locale for Chapter Title Prefixes

Set the chapter title prefixes of a report to Japanese by setting the Locale property.

import mlreportgen.report.*
rpt = Report("Japanese Report");
rpt.Locale = "ja";
house = char(23478); % Kanji character for house
append(rpt, Chapter(house));
close(rpt);
rptview(rpt); 

Version History

Introduced in R2017b

R2025a: Output reports in PDF/A format

You can output DOM and Report API reports in the PDF/A format.

R2020b: add method is not recommended

Starting in R2020b, use the append method instead of the add method to add content to objects of these Report API classes:

• mlreportgen.report.Report

• mlreportgen.report.Chapter

• mlreportgen.report.Section

• slreportgen.report.Report

To add content to a DOM API object, such as an mlreportgen.dom.Paragraph object, continue to use the append method of the DOM object. The advantage of using append to add content to Report API objects is that you use the same method name as you use to add content to DOM API objects.

There are no plans to remove the add methods of the Report, Chapter, or Section classes. Report API programs that use the add methods will continue to run.

To update existing code, replace the method name add with append as shown by the examples in the table.
